AMD Ryzen 7 4800HS vs Intel Core i7-7740X Comparison

Where Each One Wins

The benchmark data splits this comparison cleanly along workload type. The AMD Ryzen 7 4800HS claims three of the four recorded head-to-head wins, with its advantages concentrated in multi-threaded and mixed-content tasks. The Intel Core i7-7740X secures exactly one win, and it comes in a narrowly defined single-threaded scenario.

The 4800HS dominates in multi-core throughput. In Cinebench R15 multi-core, it scores 1700.5 against the 7740X’s 831, a 104.6% advantage. That is not a marginal lead; it is a doubling of rendered performance. Geekbench multi-core follows the same pattern: 7019 versus 5246, a 33.8% gap. Any workload that scales across cores, such as video encoding, 3D rendering, or compilation, will strongly favor the AMD part.

The single-core picture is more nuanced. In Cinebench R15 single-core, the 4800HS still wins, scoring 186.5 versus 117, a 59.4% margin. However, in Geekbench single-core, the Intel part strikes back: 1619 versus 1320, which translates to an 18.5% advantage for the 7740X. This suggests that the Intel chip has higher peak frequency capability in certain lightweight, latency-sensitive tasks, while the AMD part’s higher IPC and efficiency win out in the Cinebench single-thread test.

The overall database percentile rankings are nearly identical: the 4800HS sits at the 49th percentile of all CPUs, while the 7740X is at the 50th. Their average benchmark scores are also close, 2557 for AMD and 2648 for Intel, a difference of roughly 3.5%. This means that on average, the two chips are peers, but their strengths are distributed very differently. The 4800HS is the pick for parallel workloads, the 7740X for specific single-threaded tasks where Geekbench’s measurement methodology favors its architecture.

Architecture Differences

The two processors come from different design philosophies and manufacturing eras. The AMD Ryzen 7 4800HS is built on TSMC’s 7 nm process, using the Zen 2 architecture under the Renoir codename. It belongs to the 4000 series and the Ryzen 7 generation, and it is a mobile part soldered to the AMD Socket FP6. The Intel Core i7-7740X, by contrast, uses Intel’s 14 nm process, the Kaby Lake architecture, and the Kaby Lake-X codename. It is a desktop part on the Intel Socket 2066 platform, part of the X-Series 7th Gen lineup.

Core and thread counts differ substantially. The 4800HS has 8 cores and 16 threads, while the 7740X has 4 cores and 8 threads. This doubling of cores is the primary reason for the AMD chip’s multi-threaded dominance. The Intel part compensates with higher clock speeds: its base clock is 4.30 GHz and boost is 4.60 GHz, versus the AMD chip’s 2.90 GHz base and 4.20 GHz boost. The Intel chip also has an unlocked multiplier, while the AMD part is locked.

Cache hierarchies are similar in total L3 size, with both offering 8 MB shared L3. The L1 cache is identical at 64 KB per core. L2 differs: the 4800HS has 512 KB per core, while the 7740X has 256 KB per core. This larger per-core L2 on the AMD part helps feed its wider Zen 2 execution engines. The transistor count for the 4800HS is 9,800 million on a 156 mm² die; the 7740X’s transistor count and die size are not recorded in the database.

Memory support diverges significantly. The 4800HS supports DDR4 and LPDDR4 in a dual-channel configuration, with a recorded memory bandwidth of 51.2 GB/s. The 7740X supports DDR4 in a quad-channel configuration, though its bandwidth figure is not recorded. The AMD part also includes integrated Radeon Graphics with 448 SPs, while the Intel chip has no integrated graphics. Both use PCIe Gen 3. Neither supports ECC memory.

Head-to-Head Benchmarks

The largest single delta in the comparison is Cinebench R15 multi-core. The AMD Ryzen 7 4800HS scores 1700.5, and the Intel Core i7-7740X scores 831. The delta is 104.6%, meaning the AMD chip is more than twice as fast. This result aligns with the core count disparity: 8 cores versus 4, and 16 threads versus 8. The benchmark scales almost linearly with core count in this rendering workload, and the 4800HS takes full advantage.

Cinebench R15 single-core is also a win for AMD, though by a smaller margin. The 4800HS scores 186.5 against 117, a 59.4% lead. This is surprising given the Intel chip’s higher boost clock of 4.60 GHz versus 4.20 GHz. The Zen 2 architecture’s instruction-level efficiency appears to close the clock gap and then some, at least in this specific test. The data shows that raw frequency does not always dictate single-threaded performance.

Geekbench multi-core again favors AMD: 7019 versus 5246, a 33.8% difference. The margin here is smaller than in Cinebench R15 multi-core, which suggests Geekbench’s multi-core workload is less perfectly scaled across cores. Still, the 4800HS maintains a clear lead, and the result reinforces the pattern that multi-threaded tasks belong to the AMD part.

The only Intel win is Geekbench single-core. The 7740X scores 1619, while the 4800HS scores 1320. The delta is -18.5% from the AMD perspective, meaning the Intel chip is 18.5% ahead. This is a significant reversal from the Cinebench R15 single-core result. The two benchmarks measure different workloads, and Geekbench’s single-core test appears to favor the Intel chip’s higher frequency and older, simpler pipeline. The 7740X’s 4.60 GHz boost clock likely plays a decisive role here.

The win tally is 3 to 1 in favor of the AMD Ryzen 7 4800HS. The Intel Core i7-7740X wins only the Geekbench single-core test, and even then, the AMD chip is not far behind in absolute terms. The average benchmark scores in the database, 2557 for AMD and 2648 for Intel, show that the Intel part edges ahead on average across all recorded tests, but that average is heavily influenced by the Intel chip’s Geekbench single-core score and its additional Cinebench R20 and R23 results, which the AMD part does not have recorded.

The specification table highlights the generational and platform gap. The 4800HS is a 7 nm mobile chip with a 45 W TDP, while the 7740X is a 14 nm desktop chip with a 112 W TDP. The Intel part draws significantly more power but cannot overcome the AMD chip’s core count advantage in multi-threaded tests. The AMD chip’s memory bandwidth is recorded at 51.2 GB/s, while the Intel chip’s is not recorded, though its quad-channel bus suggests high potential bandwidth. The 4800HS also carries integrated graphics and a smaller process node, which contribute to its efficiency and mobile positioning. The 7740X offers an unlocked multiplier for overclocking, a feature the locked 4800HS lacks, but the recorded benchmarks show that this does not translate into a performance win outside of Geekbench single-core.
